‘I am not a robot!’ Why did Roger Daltrey leave the stage during a Florida concert?

A nagging case of acid reflux, hearing issues or something else?

Whatever the problem was, The Who frontman Roger Daltrey wasn’t dealing Saturday night. The rock legend walked off the stage about an hour into a solo concert at Ruth Eckerd Hall in Clearwater, Florida.

Audience members took videos of various snippets of his ongoing struggles and frustration.

After attempting to crank out the classic “Naked Eye,” Daltrey goes quiet, then takes the guitar off his neck and places it down by the drum set.

“I’m going to do myself some serious damage here and I’m not going to do it because I’ll never sing again,” he says into the mic hoarsely.

“Keep going!” yells someone in the audience.

Others clap encouragingly.

Then, Daltrey yells: “I am not a robot! I’m definitely not a robot! I’m not doing this to myself anymore.”

Ticketholders said up until that point, Daltrey, who turns 79 on March 1, had been complaining that he couldn’t hear his band.

After reportedly stopping and starting the song “Getting in Tune,” Daltrey told the crowd he hadn’t been feeling well and suffered from acid reflux, a digestive disease in which stomach acid empties into the esophagus, causing heartburn-like symptoms.

He decided to hand the reins over to guitarist Simon Townshend (Pete Townshend’s baby brother) for “Goin’ Mobile” then returned, but didn’t last long.

Safe to say, many concertgoers who paid up to $200 a pop weren’t pleased. Under Ruth Eckerd’s original Facebook announcement about the concert, disappointed fans complained in the comments section, some asking for at least a partial refund.

A spokesperson for the hall did not respond to a Miami Herald inquiry on Monday.

“It was a bummer that the concert ended early,” wrote another social media user. “We have seen Roger and The Who numerous times and this has never happened. He must not have felt good at all. Hopefully, he is OK.”

“It was a great show while it lasted,” griped another. “Can’t believe he said what he did & LEFT THE STAGE! We’ve been to many shows at this venue & nothing like this has happened before. I hope all works out for Daltrey’s future shows.”

So will Daltrey sing again? As for his future shows, we know he has two big gigs coming up.

The father of eight is set to sail on the Rock Legends Cruise that leaves out of Fort Lauderdale on Monday. Also aboard for backup: Deep Purple, Night Ranger and Lou Gramm.

The music icon still appears on the floating festival’s website, crediting him for founding the iconic band in 1964 in London: “In those days Roger, whose daytime job was in a sheet metal factory, even made the band’s guitars, and it was his energy and ambition that drove the group during their formative years. That same energy, coupled with his unwavering resolve, has sustained the group during periods of uncertainty ever since.”

Daltrey also is still set to perform on his own Feb 20 at Hard Rock Live at the Seminole Guiltar Hotel near Hollywood.
